Then there is this one, told to me by a friend several years ago.
A fellow answered an ad for a zoo keeper at a very special zoo. His interview went well and he was told that they needed a new person to feed the rare, immortal porpoises. The only food that they ate consisted of sea gulls.
To protect the immortal porpoises from harm, the zoo had placed two large, stately African loins on the pathway to the lagoon where the porpoises lived. The fellow was told that he had to wait until the lions were asleep so he could step over them in order get to the lagoon and feed the porpoises. The job paid very well and he accepted the position.
His first day on the job, he collected he sea gulls and prepared them for the porpoises. He fed the lions and waited for them to lay down for their afternoon nap. Once he lions were asleep, he collected the sea gulls and started down the path to the lagoon.
He stepped over the sleeping lions and made it to the edge of the lagoon and was about to feed the porpoises when FBI agents appeared out of the bushes screaming: "Hold it right there buddy, your under arrest!"
When he asked what the charge was the head FBI agent said: "Your under arrest for taking gulls across stately lions for immortal porpoises!"
Let the groaning begin.
